A large torpedo attack threatened not only direct hits but the order of a fleet advancing in columns. Independent maneuver risked collision or isolation, while maintaining line could present a simpler target; turning away could be the least damaging option. This tactical dilemma explains the value of screens and the torpedo-boat destroyer: a fast vessel that could destroy enemy torpedo boats before they fired, while retaining torpedoes of its own. The weapon therefore shaped fleet maneuver and created a new defensive ship type even when no torpedo found its target.

Massed torpedoes could force battle fleets to turn away and lose formation, while torpedo-boat destroyers were created to stop attackers before they launched.
